I-Flex design combines shared port adapters (SPAs) and SPA interface
processors (SIPs), using an extensible design that enables service prioritization for voice,
video, and data services. Enterprise and service provider customers can use the
improved slot economics resulting from modular port adapters that are interchangeable
across Cisco routing platforms. The I-Flex design maximizes connectivity options and
offers superior service intelligence through programmable interface processors, which
deliver line-rate performance. I-Flex enhances speed-to-service revenue and provides a
rich set of quality-of-service (QoS) features for premium service delivery while effectively
reducing the overall cost of ownership. This data sheet contains the specifications for the
Cisco 2-Port Channelized T3/E3 Circuit Emulation over Packet (CEoP) and ATM SPA
(Figure 1).

Product Overview
The Cisco 2-Port Channelized T3/E3 circuit emulation over packet and ATM SPA is available on
high-end Cisco routing platforms, offering the benefits of network scalability with lower initial costs
and easy upgrades. The Cisco SPA/SIP portfolio continues Cisco’s focus on investment protection
along with consistent feature support, broad interface availability, and the latest technology. The
Cisco SPA/SIP portfolio allows different interfaces (Packet over SONET/SDH [POS], ATM,
Ethernet, etc.) to be deployed on the same interface processor.
